Another aspect could be the relationships Deku forms in the office. There could be a love interest who initially sees him as just an ordinary guy but then falls for him as she witnesses his heroics. Also, his relationships with his superiors and subordinates in the office might change. His superiors might start to rely on him more for security - related matters, and his subordinates could look up to him as a role model. All these elements combined would make for an interesting fanfiction plot.
The fanfiction might focus on Deku's character growth in this new and unexpected environment. He could start off as the clumsy, underestimated office worker but then slowly reveal his heroic qualities. For example, he might use his intelligence to outwit villains who target the office's valuable information or use his physical abilities to protect his colleagues from danger. And along the way, he may gain the respect and admiration of his co - workers who previously had no idea of his heroic potential.
Obviously, Deku is one of the main characters. He's the one around whom the whole 'accidental hero' concept revolves.
One possible plot could be that Villain Deku is on a mission to undermine the hero society and crosses paths with Hero Deku. They engage in a fierce battle where Villain Deku taunts Hero Deku about his ideals. In the end, Hero Deku manages to get through to a small part of Villain Deku's conscience, leaving him with some doubts about his villainous path.
A possible plot is that Villain Deku has a plan to destroy a major hero institution, and Hero Deku has to stop him. But when they meet, Hero Deku realizes that Villain Deku was once like him, full of hope. This makes Hero Deku hesitant to fight at full force. Or perhaps Villain Deku has kidnapped someone close to Hero Deku, and during the rescue mission, Hero Deku tries to convince Villain Deku to change his ways. Also, they could be from alternate universes where the roles are reversed, and they are forced to interact and learn from each other.
Since it's a fanfiction related to 'The Office', 'Accidental Harmony' might deal with the comical and often chaotic world of the office setting. It could be that the story features characters who, through some accident or chance event, create a harmony that is out of the ordinary for the usually dysfunctional office environment. For example, two rivals might accidentally find common ground and start getting along, which then leads to a series of interesting events that are both humorous and engaging, as is typical of 'The Office' - themed stories.
In a 'My Hero Academia Noumu Deku' fanfiction, the plot could involve Deku being turned into a Noumu - like creature against his will. This transformation could lead to him being shunned by society at first. However, he could use his newfound strength, along with his unwavering hero spirit, to prove that he's still a hero at heart. He might team up with some unlikely allies, like villains who also oppose the unethical experiments that created him.
One possible plot could be Deku facing a villain who has the ability to manipulate air or oxygen levels. Deku has to use his quick thinking and newfound control over One For All in a low - oxygen environment. Maybe he discovers a new aspect of his power that allows him to function better on less oxygen.
Well, in a Deku kidnapped fanfiction, perhaps an anti - hero group kidnaps him. They might see Deku as a symbol of the hero system they oppose. They could hold him hostage to make demands on the hero society, like changes in how heroes are regulated. Or it could be a rival from his school days who is jealous of Deku's success and kidnaps him out of envy.
For an 'accidental hero fanfic', think about a situation where a character doesn't mean to be heroic but circumstances make them so. A gardener could be watering plants when he discovers a strange object buried in the soil. It turns out to be an ancient artifact with magical powers that he unwittingly uses to save his town from a natural disaster. Or perhaps a taxi driver who picks up a passenger who is actually a wanted criminal on the run. The driver unknowingly takes a wrong turn that leads to the criminal being caught by the police. Another idea is a waitress in a diner who overhears a conversation between two villains planning a bank robbery. She accidentally spills coffee on them, causing a commotion that alerts the authorities and thwarts the robbery.
One idea could be Deku and Tsuyu teaming up for a special mission in a new and dangerous part of the city. They have to rely on each other's quirks to overcome various obstacles and villains. Another plot could be a story where Tsuyu helps Deku train a new aspect of his quirk that he's been struggling with. Maybe she uses her frog - like abilities to teach him about balance and agility.
One idea could be that Deku gets tired of being constantly underestimated and bullied despite his efforts to be a hero. So, he decides to use his knowledge of hero strategies against them and becomes a villain. He could form his own group of outcasts who were also treated unfairly in the hero - centered society.
